Get custom field entry data on before_channel_entry_delete hook

I’m using the hook before_channel_entry_delete to get custom fields of the deleted entry and use that in another context. But, when I add the hook method and try to get data, all the the custom field values are empty. For example, the hook method I’m using:

public function hook_before_channel_entry_delete($entry, $values) {
    // Trying to get custom field from $entry
    $field = $entry->getCustomField('field_id_325');
    $value = $field->getData();
    echo 'value field_id_325 - ' . $value;
    // Trying to get custom field from $entry
    print_r($values);
    die('TESTING');
}

Everything is empty. I was able to use a workaround by commenting the line: 107 in file /system/ee/EllisLab/ExpressionEngine/Model/Content/ContentModel.php $this->deleteFieldData(); To prevent deleting data.

Then in the hook method I added:

$entry_tmp = ee('Model')->get('ChannelEntry', $entry->entry_id)->first();
$field = $entry_tmp->getCustomField('field_id_325');
$value = $field->getData();
echo 'value entry_tmp - ' . $value;

In this way I was able to see the value correctly. But I feel that this is not the best, also I don’t want to edit core code. Do you have any suggestions?
